I have read the documentation but I can't quite seem to get the skipPrefix to work with xml2js. What I would like do to do is given the following xml remove the namespace prefix.
<root>
<part:tire>A</part:tire>
</root>
I would like the json object to exclude "part:".
Thanks
From the source code
prefixMatch = new RegExp(/(?!xmlns)^.*:/);
...
exports.stripPrefix = function(str) {
return str.replace(prefixMatch, '');
};
i think your xml string need to have proper namespace in order for that feature to work.

I'm trying to register a property from a const in a .ts file. I stringified the file through readFileSync.
The const look like this :
environment = {
prop1: value,
prop2: env.prop,
propArray: ['','',''],
prop: host + 'somestring',
cancelLink: 'myvaluetocatch'
};
What regex would match with 'myvaluetocatch' associated with the cancelLink prop ?
If you have a way to parse a const from a .ts file without using import, could be great too :p
Thanks for your help.
You could use cancelLink: '(.*?)', but this is fragile and depends greatly on the style of the code you have written in your file and may produce false matches.

I need to add System.Web.Script.Serialization and System.Web.Extensions to my function app so that I can deserialize json string using the following code :
JavaScriptSerializer serializer = new JavaScriptSerializer();
dynamic item = serializer.Deserialize<object>("{ \"test\":\"some data\" }");
string test= item["test"];
This does not work :
#r "System.Web.Script.Serialization"
#r "System.Web.Extensions"
How do I add resolve this issue?
I can't get that work, so I ended up using Newtonsoft Json serializer/deserializer. What you need to do is, follow this instruction to upload project.json file to your function app with this content -
{
"frameworks": {
"net46":{
"dependencies": {
"Newtonsoft.Json": "9.0.1"
}
}
}
}
This basically creates dependency. Then add this name space to your code : "using Newtonsoft.Json.Linq". Voila, you can convert your json string to object like this :
dynamic item = JObject.Parse("{number:1000}");
log.Info($"My number is: {item.number}");
The initial reference likely failed because you were trying to add an assembly reference to System.Web.Script.Serialization, which is a namespace. Adding a reference to System.Web.Extensions should work, but using Json.NET is recommended anyway.
I'm writing a Spring Boot app and need the flexibility of controlling my logback configuration using Groovy. In Spring Boot all I have to do is create src/main/resources/logback.groovy and it is automatically used for configuration.
What I would like to do though is start with Spring Boot's default logback configuration, and just override or modify settings as needed.
If I were using logback.xml instead of logback.groovy I could do something like the following.
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<include resource="org/springframework/boot/logging/logback/base.xml"/>
<logger name="org.springframework.web" level="DEBUG"/>
</configuration>
Is there something similar to the include line above that I can use in logback.groovy? I can look at the contents of base.xml and it's other included files to see how to replicate this manually, but it would add a bit of boilerplate code I'd like to avoid.
Thanks for any help you can provide.
There's an online tool that translates given logback.xml file to equivalent logback.groovy. In your case it resulted in:
//
// Built on Thu Jul 16 09:35:34 CEST 2015 by logback-translator

import static ch.qos.logback.classic.Level.DEBUG
logger("org.springframework.web", DEBUG)
When it comes to <include> it's not supported for groovy configurations.
How do you feel about instead of adding/overriding your configuration, you reload it again?
You can create a Spring Bean that will see if a logback file is in a location you specify, and if it is, reload using that file
Example
#Component
public class LoggingHelper {
public static final String LOGBACK_GROOVY = "logback.groovy";
#PostConstruct
public void resetLogging() {
String configFolder = System.getProperty("config.folder");
Path loggingConfigFile = Paths.get(configFolder, LOGBACK_GROOVY);
if (Files.exists(loggingConfigFile) && Files.isReadable(loggingConfigFile)) {
LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory();
ContextInitializer ci = new ContextInitializer(loggerContext);
loggerContext.reset();
try {
ci.configureByResource(loggingConfigFile.toUri().toURL());
} catch (JoranException e) {
// StatusPrinter will handle this
} catch (MalformedURLException e) {
System.err.println("Unable to configure logger " + loggingConfigFile);
}
StatusPrinter.printInCaseOfErrorsOrWarnings(loggerContext);
}
}
}
I am using this snippet to start my logback.groovy file
import ch.qos.logback.classic.joran.JoranConfigurator
import org.xml.sax.InputSource
def configurator = new JoranConfigurator()
configurator.context = context
def xmlString = '<?xml version="1.0" encoding="UTF-8"?>\n<configuration>\n <include resource="org/springframework/boot/logging/logback/base.xml"/>\n</configuration>'
configurator.doConfigure(new InputSource(new StringReader(xmlString)))
Contrary to the documentation stating that:
Everything you can do using XML in configuration files, you can do in
Groovy with a much shorter syntax.
include is not possible with Groovy out-of-the-box. However, thanks to a bug ticket that was opened in 2014, there are a couple of workarounds. I am including them here (slightly edited), but all credit goes to "Yih Tsern" from the original JIRA bug:
logback.groovy
include(new File('logback-fragment.groovy'))
root(DEBUG, ["CONSOLE"])
def include(File fragmentFile) {
GroovyShell shell = new GroovyShell(
getClass().classLoader,
binding,
new org.codehaus.groovy.control.CompilerConfiguration(scriptBaseClass: groovy.util.DelegatingScript.name))
Script fragment = shell.parse(fragmentFile.text)
fragment.setDelegate(this)
fragment.run()
}
logback-fragment.groovy:
// NOTE: No auto-import
import ch.qos.logback.core.*
import ch.qos.logback.classic.encoder.*
appender("CONSOLE", ConsoleAppender) {
encoder(PatternLayoutEncoder) {
pattern = "%d [%thread] %level %mdc %logger{35} - %msg%n"
}
}
Given the workaround and a pull-request to add the feature, I'm not sure why the functionality hasn't been added to Logback core yet.
I have a RazorHelpers.cshtml file in app_code which looks like:
#using Molecular.AdidasCoach.Library.GlobalConstants
#helper Translate(string key)
{
#GlobalConfigs.GetTranslatedValue(key)
}
However, I have a case where I want to use the result as the link text in an #Html.ActionLink(...). I cannot cast the result to a string.
Is there any way to return plain strings from Razor helpers so that I can use them both in HTML and within an #Html helper?
Razor helpers return HelperResult objects.
You can get the raw HTML by calling ToString().
For more information, see my blog post.
I don't think there is a way to make #helper return other types than HelperResult. But you could use a function with a return type of string, e.g.
#functions {
public static string tr(string key) {
return GlobalConfigs.GetTranslatedValue(key);
}
}
then
#Html.ActionLink(tr("KEY"), "action", "controller")

edit: MVC Razor: Helper result in html.actionlink suggests your helper can return a string by using #Html.Raw(GlobalConfigs.GetTranslatedValue(key));
In your case, I think this would also work:
#(GlobalConfigs.GetTranslatedValue(key))
Additional sample:
#helper GetTooltipContent()
{
if(Model.SubCategoryType == SUBCATTYPE.NUMBER_RANGE)
{
#(string.Format("{0} to {1}", Model.SubCategoryMinimum, Model.SubCategoryMaximum))
}
else if(Model.SubCategoryType == SUBCATTYPE.NUMBER_MAXIMUM)
{
#("<= " + Model.SubCategoryMaximum)
}
else if(Model.SubCategoryType == SUBCATTYPE.NUMBER_MINIMUM)
{
#(">= " + Model.SubCategoryMinimum)
}
}
The following statements have been validated against MVC version 5.2.4.0. I am mostly targeting the part with: Is there any way to return plain strings from Razor helpers so that I can use them both in HTML and within an #Html helper?
I did some research on how the built in MVC helpers work and they are actually properties of System.Web.Mvc.WebViewPage class, so they have nothing to do with #helper feature.
Any #helper encodes strings as HTML and works as if the code is copy pasted to the View inside a Razor code block, aka #{ code }. On the other side, #functions are supposed to be used inside Razor blocks.
Well, if a #helper works as if the code is copy pasted, why not use #Html.Raw("<p>cool</p>")? Because the Html property is null inside helpers. Why? I have no idea.
Ok, but we can use a function to return a string and then apply #Html.Raw on the result. Does that work? Yes, it does. The following example creates a <p> element in the DOM:
#functions
{
static string GetString()
{
return "<p>awesome</p>";
}
}
#Html.Raw(GetString())
If you don't understand why #Html.Raw is necessary, please read this fine article from #SLaks about Razor automatic HTML encoding.
What about the approach with the built in properties? Yes, it is possible to create static classes with public methods that work just like that. The only problem is that you have to include the namespace in the View, with the #using keyword. Can that be improved? Yes, by adding the namespace in the Web.config within the Views folder. Example:
Helpers/Global.cs
namespace WebApp.Helpers
{
public static class Global
{
public static IHtmlString GetString()
{
return new HtmlString("Something <b>cool</b>");
}
}
}
Views/Web.config
<?xml version="1.0"?>
<configuration>
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.4.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="System.Web.Mvc.WebViewPage">
<namespaces>
<!-- Add to the end of namespaces tag. -->
<add namespace="WebApp.Helpers" />
Usage
#Global.GetString()
What is the outcome? The text Something and an additional <b> element will be found in the DOM. If you need access to the Request, simply add an HttpContextBase parameter to the helper method and pass the WebViewPage.Context property when calling it.
Can it get better? Yes, as always. The same output can be created with #helper and #functions:
#helper GetString1()
{
#(new HtmlString("Something <b>awesome</b>"))
}
#functions {
public static IHtmlString GetString2()
{
return new HtmlString("Something <b>awesome</b>");
}
}
#MyHelper.GetString1()
#MyHelper.GetString2()
Answer
Regarding OP's question, I recommend #Spikolynn's approach to create a function that returns string. However, if you need to write many lines of C# code in the helper, I suggest using a static class helper.
I have read the tutorial on XML parsing in Bada. But I don't want to use a file. I need to parse my XML from a Osp::Base::String. Any ideas which methods should I use? So far I have replaced
xpathCtx = xmlXPathNewContext(doc);
if(xpathCtx == NULL) {
AppLog("Error: unable to create new XPath context");
xmlFreeDoc(doc);
return(E_IO);
}
with
xpathCtx = (xmlXPathContextPtr) xmlXPathNewCString("<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?><title lang=\"en\">XQuery Kick Start</title><title lang=\"en\">Learning XML</title>");
But the emulator simply closes.
Thank you.
Your code is wrong because you cannot cast from xmlXPathObjectPtr to xmlXPathContextPtr: they are different structs.
The code given in the tutorial is right, just use
xmlDocPtr xmlReadDoc (const xmlChar * cur,
const char * URL,
const char * encoding,
int options)
instead of
xmlReadFile(..)
To understand how to use this function have a look at the docs and at the examples on libXML2 website.
